CO Detectors (Carbon Monoxide) and CO2 (Carbon Dioxide) are not the same

CO detectors (Carbon Monoxide)  and CO2 (Carbon Dioxide) are completely different. You can buy inexpensive $45 dollar CO detectors at a hardware store but they do not tie into a system they just sound locally. A system detector will cost around $100-$150 and a carbon Dioxide CO2 detector/sensor can run over $500-$700 each. </h1><h1>
